Description
The Dormer Pramet R520 8.20 mm carbide straight-shank stub drill is built for reliable, precise hole making across a range of metals. With a DIN 6539 straight shank, it fits standard chucks and holders, making it a versatile choice for workshops, job shops, and maintenance teams.
A 130° point helps with self-centering and reduces the push force required for start-ups, promoting clean starts and smoother drilling. The Titanium Nitride (TiN) coating extends tool life and improves performance when drilling harder materials, while convex cutting edges aid chip control and enable higher speeds and feeds for faster material removal.
- 130° Self-Centering Point: Promotes clean starts and reduces operator effort by guiding the drill into the workpiece with less wandering.
- TiN Coating for Longer Life: Titanium Nitride reduces wear and friction, extending service life and sustaining performance on tougher materials.
- Convex Cutting Edges for Chip Control: Improves chip breaking and evacuation, allowing higher cutting speeds and feeds for faster, more efficient drilling.
Designed to drill a wide range of materials—steel, aluminium, and stainless steel—the R520 delivers consistent, high-quality holes with h8 tolerance even at higher speeds and feeds. Its premium carbide core, TiN coating, and precise geometry work together to minimize downtime, reduce tool changes, and produce reliable results in production runs, maintenance tasks, and precision projects alike.
